application where vacuum adsorption of a workpiece is confirmed by a

Pressure switch.

B Bottom value display Displays the minimum pressure reached up to that moment.

ChatteringThe problem of the switch output turning ON and OFF repeatedly around the

set value at high frequency due to the effect of pulsation.

Chattering prevention functionA function to delay the response time of switch output in order to prevent

chattering.

C

Copy functionA function to copy a pressure setting value and function setting (excluding fine

adjustment of display value).

D

Digit (Minimum setting unit)

Shows how precisely the pressure can be displayed or set by the digital

Pressure switch. When 1 digit=1 kPa, the pressure is given with an increment

of 1kPa, e.g., 1, 2, 3, , 99, 100.

EError indication

With the self-diagnostic function of the Pressure switch, this indicates that thereis an error which could cause a switch failure.

Fine adjustment mode Refer to "Fine adjustment of display value".

Fine adjustment of display value

A displayed pressure value can be adjusted within the range of 5%R.D.

(5% of the displayed value). It is used if a true pressure value is known or to

correct the difference of a displayed value of the measurement equipment

nearby which measures the same pressure.

F.S. (full span/full scale)

Abbreviation for full span or full scale; this means the maximum fluctuation

range of the Pressure switch rated value. For example, when the output

voltage is 1 to 5[V], the F.S. will be 5-1=4[V]. (Ref: 1%F.S.=4 0.01=0.04[V])

F

Function selection mode

This is a mode in which each function is set up, and is a separate menu fromthe pressure setup. If the setting needs to be changed, "F*", each item can be

set up. The items to be set up are: display colour, operation mode, output type,

response time, display resolution, fine adjustment of display value, auto preset,

power-saving mode and security code number.

1/1000.)

Indicator LED The LED that turns on when the switch output is on.

I

Indication unit The unit of pressure used on the display.

KKey lock (function)

A function that locks the setting buttons so that no accidental setting changes

can be made.

L Load impedance Refer to "Max. load impedance".

Manual set upManual pressure set up without using auto preset. This term is used to

distinguish from the pressure set up using auto preset.

Master Pressure switch A Pressure switch whose settings are copied when using the copy function.

Max. applied voltageThe maximum value of applied voltage available to the output wire of the NPN

output.

Max. load current The maximum current available to the output wire of the switch output.

connected to the output (output wire) of the analogue current output.

Measurement modeThe condition in which the pressure is detected and displayed and the switch

output is operating.

M

Min. setting unit Refer to "digit".

Normal output

The switch output operation in which the switch is turned on when pressure

equal to or greater than the set value is detected. In the (hysteresis mode)

window comparator mode, it is the operation in which the switch is turned on

when pressure is within the switch output range (P1L to P1H or P2L to P2H).

(Refer to "List of output modes" on page 29).

N

NPN (open collector) output The switch output which uses the NPN transistor for output.

Operating mode There are two choices, hysteresis mode and window comparator mode.

Output impedance

The resistance value of a component between the voltage output element and

the analogue voltage output. It is indicated as a resistance value which is

converted in accordance with the condition in which resistance is directly

connected to the voltage output element. There may be an error in the output

voltage depending on this output impedance and the input impedance of

customers' equipment. (example: If the Pressure switch with output impedance

of 1 k is connected to the A/D converter to detect the analogue output of 5 V,

the detected voltage by the A/D converter becomes 5(V) 1(M)/(1(k) +

1(M))4.995(V), and there is an error of approximate 0.005 V).

O

Output typeThe operation type of the switch output. Either normal output or reversed

output can be selected. (Refer to "List of output modes" on page 29).

Peak value display Displays the maximum pressure reached up to that moment.

Wiring

ConnectionConnections should only be made with the power supply turned off.

Use a separate route for the Pressure switch wiring and any power or high voltage wiring. Otherwise,

malfunction may result due to noise.

Ensure that the FG terminal is connected to ground when using a commercially available switch-mode

power supply. When a switch-mode power supply is connected to the product, switching noise will be

superimposed and the product specification can no longer be met. This can be prevented by inserting a

noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and the

product, or by using a series power supply instead of a switch-mode power supply.

Connector

Connecting/Disconnecting

When mounting the connector, insert it straight into the socket, holding the lever and connector body, and

push the connector until the lever hooks into the housing, and locks.

When removing the connector, press down the lever to release the hook from the housing and pull the

connector straight out.
